Tony Ryan Wood Extender works pretty good and feels like a cue when you grip it.
It comes in two sizes; 12” and 18”. Anything more than that feels awkward and then
I revert to a bridge but that doesn’t happen very often and shouldn’t if you get shape.
I think this question also depends where you play. I use a butt extension, because I regularly find myself in situations where I need to remove it in places where tables are close to walls.
